Abstract

The present disclosure relates to methods for treating deactivated SCR catalysts having an increased SO2/SO3 conversion rate as a result of the accumulation of one or more iron compounds. The methods are characterized in that the catalysts are treated with an aqueous solution of an acidic reactive salt or hydrogen fluoride, with the addition of at least one antioxidant.
